The results of a recent study done by the Associated Press (AP), which tested drinking water in 50 major cities in 50 states, showed that, "41 million americans drink water contaminated with antibiotics, anti-convulsants, mood stabilizers, and sex hormones." This research confirms prior studies which proved that not only pharmaceuticals, but a wide array of chemicals including, fragrances used in perfumes, shampoos, detergents, sun-blocking compounds from sunscreen lotions, personal health and beauty aids are in our water.

The U.S. Geological Survey researchers have reported, "Finding a variety of antibiotics just downstream from hospitals and treatment plants." Because of these findings, several tests were scheduled at, "100 sites in 24 states." They were particularly concerned about the water downstream from various wastewater sources. Statistics from their research showed that;

One or more chemicals were detected in 80 percent of the streams sampled, and 82 of the 95 chemicals were detected at least once.

Mixtures of the chemicals were common.

75 percent of the streams had more than one chemical, 50 percent had 7 or more, and 34 percent had 10 or more.

Though the drugs detected were in trace amounts, concern has arisen about long term effects due to disturbing animal mutations such as severe reproduction effects;

Damaged sperm

Lowered sperm count

Male fish development of female eggs

Premature spawning

According to the US Environmental Protection Agency (EPA), "The presence of contaminants does not necessarily indicate that water poses a health risk." Yet because some pharmaceuticals are documented to remain in groundwater for several years, long term effects are a cause of concern for some. The EPA sets standards for, "Approximately 90 contaminants in drinking water", which unfortunately doesn't include the regulation of pharmaceuticals. In addition, bacteria may grow resistant to antibiotics, which is always a concern. The EPA provides several tips on how to find out if your local water is safe to drink, along with information about drinking water sources.
